99 Caravan 3.3 misfire multiple cylinders again after replace coil
I have 99 Caravan 3.3L engine. The check engine light came on a while ago; scan the code, it shows #3, #6 misfire. There was occasional ruff idle. I replaced the ignition coil (BWD from advanceauto); after installation, disconnect and ground the battery to clear the code, then the check engine light went off, and car ran smoothly.
Today (4 days after I replace the coil), the car ran ruff again when I pick up the speed, the check engine light flashes, then stayed on. From my trip meter, I drove 112 miles, and 4 hour 20 minutes. Scan code shows multiple events of #3, #6 misfire, multiple cylcinder misfire.
I can replace the Coil, but before doing that, I would like to get any suggestion on what else it may be.
Thanks,
